A00033 - Ibn al-Wafid, Author of The Book of Simple Drugs

Ibn al-Wafid

Ibn al-Wafid (Ali Ibn al-Husain Ibn al-Wafid) (997-c.1074), known in Latin Europe as Abenguefit, was a pharmacologist and physician from Toledo. He was the vizier of  Al-Mamun of Toledo. His main work is Kitāb al-adwiya al-mufrada (The Book of Simple Drugs) (كتاب الأدوية المفردة, translated into Latin as De medicamentis simplicibus).

Ibn al-Wafid was mainly a pharmacist in Toledo, and he used the techniques and methods available in alchemy to extract at least 520 different kinds of medicines from various plants and herbs.

Ibn al-Wafid's student Ali Ibn al-Lukuh was the author of ʿUmdat al-Ṭabīb fī Maʿrifat al-Nabāt li kulli Labīb, a famous botanical dictionary.

Kitāb al-adwiya al-mufrada (The Book of Simple Drugs) ran to five hundred pages, taking twenty-five years to compile.  The Latin translation, De medicamentis simplicibus is only a fragment of all his work.  

As well as investigatin the action of drugs, sleep and bathing, Ibn al-Wafid also wrote on farming, because agriculture, plant cultivation, botany, chemistry and medicine were closely linked.

A00032 - Ibn al-Thahabi, Author of First Known Alphabetical Medical Encyclopedia

Ibn al-Thahabi
Ibn al-Thahabi (Abu Mohammed Abdellah Ibn Mohammed Al-Azdi) (Arabic: ابو محمد عبدالله بن محمد الأزدي‎) (ca. ? - 1033, in Valencia, Al-Andalus [Islamic Spain]), known also as Ibn Al-Thahabi, was an Arab physician, famous for writing the first known alphabetical encyclopedia of medicine.

Ibn al-Thahabi was born in Suhar, Oman.  He moved then into Basra,  then to Persia where he studied under Al-Biruni and Ibn Sina.  Later he migrated to Jerusalem and finally settled in Valencia, in Al-Andalus (Islamic Spain).

Ibn al-Thahabi is famous for his book Kitab al-Ma'a (The Book of Water), which is a 900 page medical encyclopedia that lists the names of diseases, its medicine and a physiological process or a treatment. It is the first known alphabetical classification of medical terms. In this encyclopedia, Ibn Al-Thahabi not only lists the names but adds numerous original ideas about the function of the human organs. It also contains a course for the treatment psychological symptoms. The main thesis of his medication is that cure must start from controlled food and exercise and if it persists then use specific individual medicines.  If it still persists, then use medical compounds. If the disease continued, surgery was performed.

A00031 - Ibn al-Shatir, The "Father" of Copernicus' Theory

Ala Al-Din Abu'l-Hasan Ali Ibn Ibrahim Ibn al-Shatir (1304 – 1375) (Arabic: ابن الشاطر‎) was an Arab Muslim astronomer, mathematician, engineer and inventor who worked as muwaqqit (موقت, religious timekeeper) at the Umayyad Mosque in Damascus, Syria.

Ibn al-Shatir conducted extensive observations which led to some of his theoretical contributions, designed and constructed new instruments, and made advanced contributions to Islamic astronomy in the field of planetary theory.

His most important astronomical treatise was the Kitāb Nihāyat al-Suʾāl fī Taṣḥīḥ al-ʾUṣūl (كتاب نهاية السؤال في تصحيح الأصول - The Final Quest Concerning the Rectification of Principles), in which he drastically reformed the Ptolemaic models of the Sun, Moon, and planets. While previous Maragha school models were just as accurate as the Ptolemaic model, Ibn al-Shatir's geometrical model was the first that was actually superior to the Ptolemaic model in terms of its better agreement with both contemporary theory and empirical observations. 

Experimentally Ibn al-Shatir employed careful eclipse observations to measure the apparent size of the Sun and Moon and found that they disagreed with Ptolemaic expectations. His work on his experiments and observations (e.g. Ta'liq al-arsad, or Accounting for Observations) has not survived, but there are references to it in his Final Quest Concerning the Rectification of Principles.

Theoretically, Ibn al-Shatir objected to Aristotle's ether, in its eternal uniformity, and argued that if one grants that the heavens must allow for a variation in composition then there's no reason to reject epicycles, while agreeing that equants and eccentrics, which violated Aristotelian principles of uniform circular motion and gravity, were impossible. He then built a model that by adding new epicycles utilizing the Tusi-couple eliminated entirely the epicycle in the solar model, the eccentrics and equants in the planetary models, and the eccentric, epicycles and equant in the lunar model. The resulting model was one in which the Earth was at the exact center of the universe around which all heavenly bodies moved in uniform circular motions, remained as accurate as Ptolemy in predicting the paths of heavenly bodies, and improved on Ptolemy by accurately predicting the apparent size and distance of the Sun and Moon.

By creating the first model of the cosmos in which physical theory, mathematical model, and empirical observation were in agreement, Ibn al-Shatir marked a turning point in astronomy which may be considered a "Scientific Revolution before the Renaissance".

Although his system was firmly geocentric — he had eliminated the Ptolemaic equant and eccentrics  — the mathematical details of his system encompassed those in Nicolaus Copernicus' De revolutionibus, which had retained the Ptolemaic eccentric.  Copernicus' lunar model was identical to the lunar model of al-Shatir.  It is noted that in Copernicus' Commentariolus his model of Mercury is mistaken, and that snce it is Ibn al-Shatir's model, this is further evidence, and perhaps the best evidence, that Copernicus was in fact copying without full understanding from some other source. All this suggests that Ibn al-Shatir's model may have influenced, if indirectly, Copernicus while constructing the latter's heliocentric model. How Copernicus would have come across al-Shatir's work, exactly, remains an open question, but there are some number of possible routes for first or secondhand transmission.

Ibn al-Shatir constructed a magnificent sundial for the minaret of the Umayyad Mosque in Damascus which gave both seasonal and equinoctial hours. The fragments of this sundial in a Damascus museum make this the oldest polar-axis sundial still in existence.

Ibn al-Shatir made a timekeeping device incorporating both a universal sundial and a magnetic compass. 

The compendium, a multi-purpose astronomical instrument, was first constructed by Ibn al-Shatir. His compendium featured an alhidade and polar sundial among other things. These compendia later became popular in Renaissance Europe.

Ibn al-Shatir described another astronomical instrument which he called the "universal instrument" in his Rays of light on operations with the universal instrument (al-ʾashiʿʿa al-lāmiʿa fī al-ʿamal bi-l-āla al-jāmiʿa). A commentary on this work entitled Book of Ripe Fruits from Clusters of Universal Instrument (Kitāb al-thimār al-yāni'a ʿan qutāf al-āla al-jāmiʿa) was later written by the Ottoman astronomer and engineer Taqi al-Din, who employed the instrument at the Istanbul observatory of Taqi al-Din from 1577-1580.

In the case of lunar motion, Ibn al-Shatir corrected Ptolemy, whose imagined Moon approached far closer to the Earth than did the actual Moon.

Many believe that astronomy died with the Greeks, and was brought back to life again by Copernicus, the 15th century Polish astronomer who is famous for introducing the Sun-centered (heliocentric) theory of the solar system, which marked the beginning of modern astronomy.

However, many historians now think it is not a coincidence that his models of planetary theory are mathematically identical to those prepared by Ibn al-Shatir over a century before him.  It is known that Copernicus relied heavily on the comprehensive astronomical treatise by al-Battani, which included star catalogues and planetary tables.

The mathematical devices discovered by Muslims before Copernicus, referred to in modern terms as linkages of constant length vectors rotating at constant angular velocities, are exactly the same as those used by Copernicus.  The only, but important, differences between the two was that the Muslims' Earth was fixed in space, whereas Copernicus had it orbiting around the Sun.  Copernicus also used instruments which were particular to astronomy in the East, like the parallactic ruler, which had previously only been used in Samarkand and Maragha Observatories.

A00030 - Ibn al-Saffar, Andalusian Astronomer

Ibn al-Saffar

Abu al‐Qasim Ahmad ibn Abd Allah ibn Umar al‐Ghafiqī ibn al-Saffar al‐Andalusi (b. Cordoba - d. 1035 at Denia), Ibn al-Saffar (literally: son of the brass worker) was a close colleague and astronomer at the school founded by al-Majriti in Cordoba.  His most well known work was a treatise on the astrolabe.  The work was still published until the 15th century and influenced the work of Kepler.  Ibn Saffar also wrote a commentary on the Zij al-Sindhind,  and measured the coordinates to Mecca.  

A00029 - Ibn al-Quff, Author of Basics in the Art of Surgery

Ibn al-Quff
Ibn al-Quff (1233-1286{1305?}).  Christian physician and surgeon.  He was the first known military physician surgeon and composed a manual on surgery.  The Arab physician Ibn al-Quff, a student of Ibn al-Nafis, described embryology and perinatology more accurately in his Al-Jami.

Amīn-ad-Daula Abu-'l-Faraǧ ibn Yaʻqūb ibn Isḥāq Ibn al-Quff al-Karaki (Arabic: أمين الدولة أبو الفرج بن يعقوب بن إسحاق بن القف الكركي‎)  was an Arab physician and surgeon and author of the earliest medieval Arabic treatise intended solely for surgeons.

Ibn al-Quff was born in the city of Al Karak (in modern-day Jordan). His father was Muwaffaq al-Dīn Yaʿqūb, a Christian Arab. His father had a good job opportunity and moved his family to Sarkhad in Syria, where Ibn al-Quff was tutored by Ibn Abi Uṣaybiʿah who introduced him to the medical studies. He studied with Ibn Abi Uṣaybiʿah and learned a lot of medical information, read many biographies on earlier doctors, and spent a large amount of time meditating on the material he studied and learned. Ibn al-Quff ended up moving to Damascus where he improved his knowledge and studied metaphysics, philosophy, medicine, natural sciences, and mathematics. It is not completely clear as to who was teaching him all of this material but regardless he learned a large amount of information which would be very beneficial for his career. After he had studied for a while and proved he was a good knowledgeable physician and surgeon, he was given the job of physician-surgeon in the army which was stationed in Jordan. It was while serving in the army that he became well known as a physician and a surgeon. His reputation became widespread in the Muslim empire for being a Christian Arab, for caring for his patients and for conducting his work with honesty. After his time of popularity died down he was sent to Damascus and remained there teaching until his death at the age of fifty-two.

During his time in Jordan being a physician-surgeon, Ibn al-Quff wrote many books and taught. He was more well known as a writer and educator on medical topics than for being a doctor. He wrote at least ten commentaries and books during his lifetime. Seven of these works are known to exist today whether fragments or the entire work. One of his most famous works was a commentary on Ishārāt of Ibn Sina, but there is no evidence of this today. Some of the most well known surviving works of Ibn al-Quff are listed below with a brief description.

• Kitāb al-ʻUmda fi 'l-ǧirāḥa (كتاب العمدة في الجراحة) or Basics in the Art of Surgery: a general medical manual covering anatomy and drugs therapy as well as surgical care, concentrating on wounds and tumors, however, he excluded ophthalmology as he considered it to be a specialty with its own technical literature. The work was published in Hyderabad, India, in 1937. This was by far the largest Arabic text on surgery during the entire medieval period. In this book, Ibn al-Quff explained the connections between arteries and veins which was the earliest description of what would be known as capillaries. He did this work before the invention of a microscope and also explained how valves worked and the direction they opened and closed.

• Al-Shafi al-Tibb (The Comprehensive of the Healing Arts): His first medical encyclopedia, completed early 1272 AD.

• Jāmiʻ al-gharaḍ fī ḥifẓ al-ṣiḥḥah wa-dafʻ al-maraḍ (جامع الغرض في حفظ الصحة ودفع المرض): on preventive medicine and the preservation of health in 60 chapters, completed around 1275. 

• Al-usul fi sarh al-fusul: A two-volume commentary on the works of Hippocrates.

• Risala fi manafi al-a da: A treatise on the anatomy of the body's organs.

• Zubad at-Tabib: A book with advice for practicing physicians.

• Sarh al-Kulliyat: A commentary on Avicenna's work Qanun fi t-Tibb.

A00028 - Maryam Mirzakhani, First Woman to Receive Fields Medal

Mirzakhani, Maryam

Maryam Mirzakhani (Persian: مریم میرزاخانی‎; born May 1977) is an Iranian mathematician, and a full professor of mathematics (since 1 September 2008) at Stanford University. 

Her research interests include Teichmuller theory, hyperbolic geometry, ergodic theory, and symplectic geometry.   In 2014, Mirzakhani became the first woman, as well as the first Iranian and the second person from the Middle East (after Elon Lindenstrauss), to be awarded the Fields Medal. 

Mirzakhani found international recognition as a brilliant teenager after receiving gold medals at both the 1994 International Mathematical Olympiad (Hong Kong) and the 1995 International Mathematical Olympiad (Toronto), where she was the first Iranian student to finish with a perfect score.

Maryam Mirzakhani was born in 1977 in Tehran, Iran. She went to high school in the city at the Farzanegan School, a school for gifted girls that is administered by the National Organization for Development of Exceptional Talents (NODET). Mirzakhani competed and was recognized internationally for her math skills, receiving gold medals at both the 1994 International Mathematical Olympiad (Hong Kong) and the 1995 International Mathematical Olympiad (Toronto), where she was the first Iranian student to finish with a perfect score.

Mirzakhani obtained her BSc in mathematics (1999) from Sharif University of Technology in Tehran. She went to the United States for graduate work, earning a PhD from Harvard University (2004), where she worked under the supervision of the Fields Medalist Curtis McMullen. She was also a 2004 research fellow of the Clay Mathematics Institute and a professor at Princeton University. 

Mirzakhani has made several contributions to the theory of moduli spaces of Riemann surfaces.  In her early work, Maryam Mirzakhani discovered a formula expressing the volume of a moduli space with a given genus as a polynomial in the number of boundary components. This led her to obtain a new proof for the formula discovered by Edward Witten and Maxim Kontsevich on the intersection numbers of tautology classes on moduli space, as well as an asymptotic formula for the growth of the number of simple closed geodesics on a compact hyperbolic surface. Her subsequent work has focused on Teichmüller dynamics of moduli space. In particular, she was able to prove the long-standing conjecture that William Thurston's earthquake flow onTeichmuller space is ergodic.

Mirzakhani was awarded the Fields Medal in 2014 for "her outstanding contributions to the dynamics and geometry of Riemann surfaces and their moduli spaces". She was congratulated for her win by Iranian President Hassan Rouhani.

She married Jan Vondrak, a theoretical computer scientist.  They had a daughter named Anahita.

A00027 - Ibn al-Nadim, Author of the Fihrist (The Index)

Ibn al-Nadim
Ibn al-Nadim (Abu'l-Faraj Muhammad bin Is'hāq al-Nadim) (c. 936 - September 17, 995).  Shi‘a of Baghdad and the author of an index of Arabic books.   The work, which exists in a shorter recension (a shorter critical revision), is intended to be an index of all books written in Arabic either by Arabs or non-Arabs.

Abu'l-Faraj Muhammad bin Is'hāq al-Nadim, whose father was known as al-Warrāq, was a Shi'ite Muslim scholar and bibliographer. Some scholars regard him as a Persian but this is not certain. He is famous as the author of the Kitāb al-Fihrist (The Index). His choice of the rather rare Persian word pehrest (fehrest/ fehres/ fahrasat) for the title of a handbook on Islamic literature is noteworthy in this regard.

Very little is actually known about his life. He was a bookseller, a calligrapher who copied manuscripts for sale, as his father was before him. He lived in Baghdad and sometimes he mentions a sojourn in Mosul. Of his teachers he mentions al-Sirafi (died 978-9), 'Ali bin Harun bin al-Munazhzhim (died 963) and the philosopher Abu Sulayman al-Mantiqi. He belonged to the circle of a son of 'Ali bin 'Isa the "Good Vizier" of the Banu al-Jarrah, whom he praises for his profound knowledge of the logic and the sciences of the Greeks, Persians and Indians. Ibn al-Nadim also met in his house the Christian philosopher Ibn al-Khammar. With these men, none of whom was an orthodox Sunni, he shared an admiration for philosophy and especially for Aristotle, and the Greek and Hindu sciences of antiquity (before Islam). He admired their breadth of outlook and their air of toleration.

It did not escape his biographers that he was a Shi'ite (Ibn Hajar, l.c.); he uses khassi instead of Shi'ite, 'ammi instead of Sunnite, al-hashwiyya for the Sunnis, Ahl al-Hadith ("People of the Hadith") instead of Ahl al-Sunna ("People of the Tradition"). He inserts the eulogy for prophets (consisting of the words alaihi al-salam, "peace be with him") after the names of the Shi'i Imams and the Ahl al-Bayt (the descendants of Muhammad). He calls the Imam al-Rida mawlana. He asserts that al-Waqidi was a Shi'ite but concealed this fact by taqiyya. He claims most of the (orthodox) 'traditionists' for the Zaydiyya. He speaks of the Mu'tazila as Ahl al-'Adl ("People of the justice"), calls the Ash'arites al-mujbira. That he belonged to the Twelver Shi'a is shown by his distaste for the doctrines of the Sab'iyya and by his criticisms in dealing with their history. He remarks that a certain Shafi'i scholar was secretly a Twelver Shi'ite. He mentions Shi'as among his acquaintances, e.g., Ibn al-Mu'allim, the da'i Ibn Hamdan and the author Khushkunanadh. To the same circle belonged the Jacobite Yahya ibn 'Adi (d. 973) who instructed 'Isa bin 'Ali in philosophy and who was, like Ibn al-Nadim, a copyist and bookseller.

His great book, the Fehrest or Fihrist, gives ample testimony to the knowledge of pre-Islamic Persia and its literature in classical Islamic civilization, but unfortunately only a minute sample of the numerous Persian books listed by Ebn al-Nadīm is extant. According to Fehrest's brief preface, it is meant to be an index of all books written in Arabic, whether by Persians, Arabs or others. There existed already books (tabaqat) dealing with the biographies of poets. The Fehrest was published in 938; it exists in two manuscript traditions, or "editions": the more complete edition contains ten "discourses" (maqalat). The first six of them are detailed bibliographies of books on Islamic subjects:

1. the Holy Scriptures of Muslims, Jews, and Christians, with emphasis on the Qur'an and hadith;

2. works on grammar and philology;

3. history, biography, genealogy and the like;

4. poetry;

5. dialectical theology (kalam);

6. law (fiqh) and hadith.

The last four discourses deal with secular subjects:

7. philosophy and the 'secular sciences';

8. legends, fables, magic, conjuring, etc.;

9. the doctrines (maqalat) of the non-monotheistic creeds (Manicheans, Hindus, Buddhists and Chinese);

10. alchemy.

Ibn Nadim gives the titles only of those books which he had seen himself or whose existence was vouchsafed by a trustworthy person.

The shorter edition contains (besides the preface and the first section of the first discourse on the scripts and the different alphabets) only the last four discourses, in other words, the Arabic translations from Greek, Syriac and other languages, together with Arabic books composed on the model of these translations.

Ibn al-Nadim often mentions the size of a book and the number of pages, so that buyers would not be cheated by copyists passing off shorter versions. Compare the Stichometry of Nicephorus. He refers often to copies written by famous calligraphers, to bibliophiles and libraries, and speaks of a book auction and of the trade in books. In the opening section he deals with the alphabets of 14 peoples and their manner of writing and also with the writing-pen, paper and its different varieties. His discourses contain sections on the origins of philosophy, on the lives of Plato and Aristotle, the origin of The Book of One Thousand and One Nights, thoughts on the pyramids, his opinions on magic, sorcery, superstition, and alchemy etc. The chapter devoted to what the author rather dismissively calls "bed-time stories" and "fables" contains a large amount of Persian material. In the chapter on anonymous works of assorted content there is a section on "Persian, Indian, Byzantine, and Arab books on sexual intercourse in the form of titillating stories", but the Persian works are not separated from the others. The list includes a "Book of Bahrām-doḵt on intercourse." This is followed by books of Persians, Indians, etc. on fortune telling, books of "all nations" on horsemanship and the arts of war, then on horse doctoring and on falconry, some of them specifically attributed to the Persians. Then we have books of wisdom and admonition by the Persians and others, including many examples of Persian andarz literature, e.g. various books attributed to Persian emperors such as Khosrau I and Ardashir I.
